Percy Wenrich (January 23, 1887 – March 17, 1952) was a United States composer of ragtime and popular music. Born in Joplin, Missouri, he left for Chicago in 1901 where he attended classes at the Chicago Musical College. Wenrich moved on to New York City around 1907 to work as a Tin Pan Alley composer, but his music retains a Missouri folk flavor. He composed at least eighteen rags, including “Ashy Africa,” “Noodles,” “Peaches and Cream” (1905), “Crab Apples,” and “The Smiler” (1907). His songs include “Wabash Avenue After Dark” and the hits “Put on Your Old Grey Bonnet,” “Moonlight Bay” and “When You Wore a Tulip.” Wenrich was one of the founders of ASCAP. His generous legacy still benefits The Lambs today, and he is an Immortal Lamb. He is interred in Fairview Cemetery in Joplin.
